我们提出了一个抽象的方法,系统地分配一个“理性”的排名非合理化的选择数据。我们的主要观点是,任何将个人福利作为选择函数的方法都是主观的,并且取决于进行分析的经济学家。我们提供了一个简单的例子,我们建议的运动类型。也就是说,我们定义一个个人福利功能作为一个映射从随机选择功能到弱订单。随机选择函数(或选择分布)给出了任何可能的机会集的经验选择频率(框架因素也可以并入模型)。我们要求,对于任意两个选择x和y,如果我们的个体福利泛函在给定两个不同的选择分布的情况下推荐x而不是y,那么它也会在两个选择分布的任意混合情况下推荐x而不是y。再加上一些温和的技术要求,这样的个人福利函数必须加权每个机会集,并为每个备选方案x分配效用,该效用是所有机会集上x被选择的加权概率之和。因此,它要求我们对在给定情况下选择x的重要性或代表性有一个“先验观点”。
We propose an abstract method of systematically assigning a “rational” ranking to non-rationalizable choice data. Our main idea is that any method of ascribing welfare to an individual as a function of choice is subjective, and depends on the economist undertaking the analysis. We provide a simple example of the type of exercise we propose. Namely, we define an individual welfare functional as a mapping from stochastic choice functions into weak orders. A stochastic choice function (or choice distribution) gives the empirical frequency of choices for any possible opportunity set (framing factors may also be incorporated into the model). We require that for any two alternatives x and y, if our individual welfare functional recommends x over y given two distinct choice distributions, then it also recommends x over y for any mixture of the two choice distributions. Together with some mild technical requirements, such an individual welfare functional must weight every opportunity set and assign a utility to each alternative x which is the sum across all opportunity sets of the weighted probability of x being chosen from the set. It therefore requires us to have a “prior view” about how important or representative a choice of x at a given situation is.
